AGP = basal feeds supplemented with antibiotics as a growth promoter (amoxicillin and colistin) at 300 ppm from the suckling phase to the grower phase; NAGP = basal feeds without AGP or any feed additive from the suckling to finisher phases; HKL1 = basal feeds supplemented with HK L-137 at 20, 20, 20, 0, 0 and 0 ppm; and HKL2 = basal feeds supplemented with HK L-137 at 20, 20, 4, 4, 4, and 0 ppm during the suckling phase, weaner phase, starter phase, grower phase, finisher 1 phase 1, and finisher 2 phase, respectively. SEM is the standard error mean.
